{4,4′,5,5′-Tetra­methyl-2,2′-[1,1′-(ethane-1,2-diyldinitrilo)diethyl­idyne]diphenolato}nickel(II)–methanol–chloro­form (1/1/1)

In the title compound, [Ni(C(22)H(26)N(2)O(2))]·CH(3)OH·CHCl(3), the Ni(II) ion is in a slightly distorted square-planar geometry involving an N(2)O(2) atom set of the tetra­dentate Schiff base ligand. The asymmetric unit contains one mol­ecule of the complex and one mol­ecule each of chloro­form and methanol. The methanol mol­ecule is hydrogen bonded to the phenolate O atoms. In the crystal structure, short inter­molecular distances between the centroids of six-membered chelate rings [3.7002 (9) Å] indicate the presence of π–π inter­actions, which link the mol­ecules into stacks along the a axis. In addition, there are Ni⋯Ni distances which are shorter than the sum of the van der Waals radii of two Ni atoms. The crystal structure is further stabilized by inter­molecular O—H⋯O and C—H⋯O hydrogen bonds, and weak inter­molecular C—H⋯π inter­actions linking mol­ecules into extended one-dimensional chains along the c axis.
